查看了下相关资料，难怪觉得整个画面看起来很怪
As of version 22H2, Windows 11 does not allow us to pick which tone curve to use for SDR — in fact it uses neither of the above. Instead, Windows 11 uses what's called the piecewise sRGB transfer function, originally intended for computer/web use. This curve is technically the tone response that gamma 2.2 approximates, but for various reasons it wasn't commonly used as an actual display EOTF. Gamma 2.2 took over as the pseudo-standard, and almost every computer monitor still uses it to this day.
从版本 22H2 开始，Windows 11 不允许我们选择用于 SDR 的色调曲线 - 事实上它不使用上述两者。相反，Windows 11 使用所谓的分段 sRGB 传输函数，最初用于计算机/网络使用。从技术上讲，该曲线是 gamma 2.2 近似的色调响应，但由于各种原因，它并不常用作实际显示器 EOTF。 Gamma 2.2 成为伪标准，几乎每台计算机显示器至今仍在使用它。
Because it's so prolific, almost all web content and computer games are color graded using a gamma-2.2 outputting monitor, intentionally or not. For Microsoft to decide using piecewise sRGB as the virtual SDR curve was a mistake; it forcibly renders almost all apps and web content to look incorrect, some more than others.
由于内容丰富，几乎所有网页内容和电脑游戏都有意或无意地使用 gamma-2.2 输出显示器进行颜色分级。对于微软来说，决定使用分段 sRGB 作为虚拟 SDR 曲线是一个错误；它强制使几乎所有应用程序和网页内容看起来不正确，其中一些比其他内容更不正确。
On the other hand, there have been countless complaints about the game looking washed out when HDR is enabled, swaying many players to simply enjoy the game in SDR. When HDR is enabled, rich blacks turn into dull grays, and the game's atmosphere turns hazy, losing much of its depth. The primary cause of this is — you guessed it — the piecewise sRGB tone curve that Windows uses in HDR.
另一方面，无数人抱怨启用 HDR 后游戏看起来有些褪色，这使得许多玩家只能在 SDR 中享受游戏。启用 HDR 后，浓郁的黑色会变成暗淡的灰色，游戏的氛围变得朦胧，失去了很多深度。您猜对了，造成这种情况的主要原因是 Windows 在 HDR 中使用的分段 sRGB 色调曲线。
这也是为什么开启HDR后观看SDR内容的时候发现暗部细节变好的原因。

看大家这么多吐槽hdr的，但我觉得我买的tcl 85q10g pro 效果挺好的啊
